Development of a Parallel Radiofrequency Transmission Subsystem for MRI at 3 Tesla

Per Vices Corporation是一家总部位于多伦多的公司，生产高质量的软件定义无线电（SDR）设备。从历史上看，无线电由具有不同信号处理功能的多个电子组件组成; SDR现在使大部分硬件能够使用个人计算机进行简化和执行，与嵌入在一个电子设备中的实时计算机进行通信。广泛的软件现已广泛用于操作SDR的许多商业应用，例如智能化和安全。Per Vices有兴趣将其设备的市场扩展到医疗保健领域。特别地，射频传输是临床磁共振成像（MRI）系统的关键要素。PerVices希望联合收割机将他们在SDR方面的专业知识与MRI物理学家和工程师Simon Graham博士的专业知识相结合，以便在这种情况下使用Per Vices技术。Per Vices和Graham博士将进行初步研究和开发，以验证和确认该公司的“Crimson SDR”设备有助于在临床级MRI系统上使用一种名为并行射频传输（PTX）的新兴技术。PTX具有改善临床MRI功能的巨大潜力，但使能基础设施并不广泛可用。如果成功，Crimson SDR将成为新PTX硬件产品的核心组件，该产品将出售给研究MRI社区，并最终出售给跨国MRI系统供应商。

Per Vices Corporation is a Toronto-based company that makes high quality software defined radio (SDR)devices. Historically, radios consisted of multiple electronic components with different signal processingfunctions; SDR now enables much of this hardware to be streamlined and performed using a personalcomputer, in communication with a real-time computer embedded in one electronic device. Extensive softwareis now widely available to operate SDRs for many commercial applications, for example intelecommunications and in security.Per Vices is interested in expanding the market for its devices into the healthcare sector. In particular,radiofrequency transmission is a critical element of clinical magnetic resonance imaging (MRI) systems. PerVices hopes to combine their expertise in SDR with that of Dr. Simon Graham, an MRI physicist and engineer,to enable use of Per Vices technology in this context. Per Vices and Dr. Graham will undertake initial researchand development to verify and validate that the company's "Crimson SDR" device facilitates an emergingtechnique called parallel radiofrequency transmission (PTX) on a clinical-grade MRI system. PTX hassubstantial potential to improve clinical MRI capabilities, but the enabling infrastructure is not widelyavailable. If successful, the Crimson SDR could become the central component of a new PTX hardwareproduct that could be sold to the research MRI community, and ultimately to multi-national MRI systemvendors.
